Description
Technical Field
The invention belongs to the technical field of wireless communication, and particularly relates to a device and a method for realizing network connectivity detection of a fusion type set top box.
Background
The network of the set-top box unit is connected with the gateway unit and is directly communicated physically, and no physical independent interface exists externally; the set-top box unit cannot physically sense the network cable plugging or the optical fiber plugging of the gateway unit, and the gateway unit is required to inform the set-top box unit after detecting the network change condition; the network is the basis for realizing all other functions, so that the situation that the gateway unit informs the set-top box unit of the network change becomes a key and important technology, and the currently adopted technical scheme mainly comprises the following two modes:
1. through the ping mode, namely through the IP address or the domain name address appointed by ping, when the ping passes through the address, the network is considered to be passed; however, when this method is used, the ping address really exists, and if the IP or domain name fails in the using process, or if the IP and domain name address start to ping after being used for a while, the network state cannot be correctly judged by using the above method.
2. The network card two-layer data exchange mode is characterized in that the network card of the set top box unit is connected with the network card of the gateway unit, data transmission between the network card of the set top box unit and the network card of the gateway unit is completed through two-layer data exchange by using a socket, and the communication state of a network is informed; although network state data transmission can be completed through socket communication, data errors or delay can occur in the data transmission process, and certain influence is exerted on the accuracy and timeliness of network state judgment of the set top box unit. The most important point is that the mode is realized through an application layer, cannot be associated with a network mechanism of an Android system, and cannot trigger a network broadcast notification mechanism of the Android system.
Based on the above, there is a certain limitation to the sensing of the network state of the set-top box at present.

All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
The invention is described in further detail below with reference to the accompanying drawing 1:
a device for realizing network connectivity detection of a fusion type set top box comprises a set top box unit and a gateway unit, wherein a GPIO (general purpose input/output) interface of a CPU (central processing unit) of the gateway unit is used as an output port to be connected with the GPIO interface of the CPU of the set top box unit, and the set top box unit converts received high and low level signals into corresponding network state data.
The GPIO interface of the CPU of the designated gateway unit is connected with the GPIO interface of the CPU of the set-top box unit, the GPIO interface of the CPU of the gateway unit is set to be in an output mode, the GPIO interface of the CPU of the set-top box unit is set to be in an input mode, the initialization of the gateway unit is completed in the process of powering on and starting the fusion type set-top box, the designated GPIO interface is pulled up and output at a high level after the network work is ready, the GPIO interface of the set-top box unit receives the input high level, the network is considered ready, and the system informs a kernel of starting the network connection work. If the network cable or the optical fiber of the gateway unit is not accessed in the starting-up stage, the GPIO interface of the set-top box unit has no level input, and the network part is always in a disconnected state;
when the fusion type set top box is used, a network cable or an optical fiber of the gateway unit is unplugged, the GPIO immediately outputs low level after the gateway unit detects that the network is disconnected, and the set top box unit informs a system kernel of network disconnection after detecting that the low level is input, and the kernel performs network disconnection operation. After the network cable or the optical fiber is accessed, the GPIO immediately outputs high level after the gateway unit detects that the network connection is successful, and the set-top box unit informs the kernel network of the system of being connected after detecting that the high level is input, and restarts the network connection operation.
Based on the technical scheme, the GPIO of the gateway unit CPU and the set-top box unit CPU is directly connected, namely a virtual network card is simulated on a hardware layer, a Linux kernel interrupt mechanism is combined to connect the input signal of the virtual network card with the network card interrupt number of the real network card of the set-top box unit, when the GPIO input signal is changed, the operation of disconnecting the network card of the set-top box unit is realized, then the kernel network interrupt mechanism is triggered, the Android system is informed through the kernel, and the kernel is further associated with the network management mechanism of the Android system; therefore, the current network change condition can be judged in time based on the application developed by the Android network mechanism. In addition, the method and the device utilize an interrupt response mechanism of the Linux kernel to quickly and accurately respond to the plugging and unplugging condition of the network cable or the optical fiber of the gateway unit and the change of the network state.
Referring to fig. 1, a method for implementing network connectivity detection of a fusion-type set top box includes the following specific implementation methods:
the fusion type set top box is powered on and started, the set top box unit is started before the gateway unit, and the network card of the set top box unit is ready;
the gateway unit is started and network preparation is successful, and the gateway unit CPU outputs high level through the GPIO interface of the gateway unit CPU;
the GPIO interface of the CPU of the set-top box unit receives the high-level signal to trigger the network card to be interrupted, and the kernel responds to an interruption mechanism to inform the system of starting network connection.
If the network cable or the optical fiber of the gateway unit is not accessed in the system starting stage, the GPIO interface of the CPU of the set-top box unit cannot detect the change of the level signal, and the network is considered to be in a disconnected state;
when a network cable or an optical fiber is unplugged, the gateway unit detects that the network connection is disconnected, the GPIO interface of the CPU of the gateway unit outputs a low level signal, and the level of the GPIO interface of the CPU of the set top box unit is pulled down, so that the detected signal is changed, the network card is triggered to be interrupted, and the kernel responds to an interruption mechanism to inform the system of network disconnection operation.
When the fusion type set top box is used, after a network cable or an optical fiber is accessed, the gateway unit detects that the network connection is successful, the GPIO immediately outputs high level, and after the set top box unit detects that the high level is input, the set top box unit informs a system kernel network that the network is connected and restarts the network connection operation.
According to the invention, data is analyzed and processed by the kernel of the set top box unit, the GPIO interface of the CPU of the set top box unit receives the change of the level signal so as to generate an interrupt, the interrupt is sent to the CPU of the set top box unit by the interrupt controller, and the GPIO interface is self-defined, so that the CPU of the set top box unit cannot make any response according to the signal received by the GPIO interface, therefore, the high level and low level signals received by the GPIO interface of the CPU of the set top box unit are associated with network interrupt or network connection, so that the plugging condition of a network cable or an optical fiber of the gateway unit and the change of the network state are responded quickly and accurately.
The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application.
